JEWELERS APPLIANCE.

To all whom it may concern.

'Be' it known that I, LEON E. BING, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Jewelers Appliances; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to jewelers appliances and has particular reference to a device for holding rings to facilitate the process of engraving, filing and polishing.

The principal object of the invention is to provide a holder which is adapted to be supported by an engravers block of the ordinary construction and which will'obviate the necessity of the engraver holding the work in his hand when working upon the same.

Another object of the invention is to construct a holder in such a way so that the same may be rotated at will without the necessity of unclamping it from the engravers block. Broadly, this object is attained by rotatably mounting a large ring within a base, said base being adapted to be detachably secured to the engravers block.

Another object of the invention is to provide an eflicient means for securing the work within the large ring and this is done by adjustably mounting a plurality of regularly spaced arcuate ring clamps in said ring.

A still further object of the invention is to provide a device made of a few number of parts which may be easily detached and replaced when they become old or worn.

The advantages of this device will be readily apparent when it is seen that the necessity of handling the work is entirely obviated, for in polishing and butting the inside of a ring it sometimes becomes too hot to handle when it is necessary to turn the same so that it can be more readily worked upon. It will also be apparent that this device will greatly facilitate engraving and filing work which may be secured therein.

In carrying out the objects of this invention generally stated above it will be understood, of course, that the essential features thereof are susceptible to changes in detail and structural arrangements, preferred and Specification of Letters Patent.

practical embodiments being shown in the accompanying drawings wherein Figure 1 is a perspective view of the invention showing the same attached to an engravers block. Fig. 2 is a view in side elevation and partly in section showing the means for adjustably mounting the clamps in the ring. Fig. 3 is a transverse sectional view taken on the line 3-3 of Fig. 2, and, Fig. 4 is a modified form of the means for rotatably mounting the ring in its base.

Referring to the drawings by numerals it will be seen that the "improved device is adapted to be supported by an engravers block 5 having in the top thereof a transverse groove 6. The base 7 is adapted to be seated in the groove 6 and in the preferred form, this base is made in three parts, namely: a bottom strip and two vertically arranged spaced apart side strips suitably secured together. The upper edge of the side strip is curved as indicated at 8 in order that the work holder proper may be freely rotated between said vertical sides. In the upper corners of each strip there is placed a guide screw 9, said screws projecting through the sides of the base and slightly past the inner walls thereof, the purpose of which will presently be described.

A large ring 10 having an annular groove 11 on each side and adjacent the outer pe riphery thereof is rotatably mounted in the base 7. The guide screws 9 are adapted to engage in the grooves 11 thereby forming an efficient means for holding the ring 10 within its base and also guiding the same. At regularly spaced intervals the ring is provided with transverse elongated openings 12 which are adapted to receive the thumb nuts 13.

A plurality of arcuate ring clamps 14 are adapted to be adjustably mounted within the ring by means of threaded openings 15 which project from the rear surface of each clamp at right angles thereto and intermediate the ends thereof and engage the thumb nuts 13. The clamps 14 are provided at their ends with guide pins 16 which project from the rear surface of said clamps parallel to the threaded pins 15 and through transverse openings in the ring 10. These openings are for the purpose of preventing the clamps from moving laterally relatively to said ring. Each clamp is provided upon its outer bearing surface with a pad 17 which will prevent the work which is held between said clamps from becoming scarred. The inner periphery of the ring 10 is provided between two of the ring clamps 14L shown in Fig. 4., said base is made of two sections which form a channel between the vertical walls thereof. One of said walls is provided on its inner surface with an annular flange 19 which is adapted to engage one of the annular grooves 11 on the ring 10. The other groove 11 .is engagedby a screw 9 such 'as in use in the preferred form.

In use, or when it is desired toengrave, polish or file a ring, the base 7 is disposed in thegroove in the engravers block and the work is then inserted within the ring 10 and the clamps adjusted by means of the thumb nuts 13 so that said clamps will se- :curel-y hold the work in place. Vhen it is desired to move the ring in order to more readily work upon the same all that is necessary is to grasp the ring 10 and rotate the same within its base.

It will thus beseen from the'foregoing 'description'that thefinvention provides a simple and Very effective appliance for holding rings while being worked upon. It will be understood, of course, that this device may be made of any suitable material and may also be made in difierent sizesalthough it may be made in just one size which will accommodate any size. 1

Having thus described the'invention what is-olaimed is :f j

1. A deviceof the class described comprising a base having upwardly extending spaced walls, a ring interposed between said walls, means to holdsaid ring in adjusted position between said walls, and adjustable 1 work clamping means carried by said ring.

A- device of the classdescribed comprising a base having upwardly extending spaced walls, a ring interposed between said walls, said ring having a groove around'one side,

means extending inwardly from one wall and into said groove adapted to guide and support said ring, and means carried by the other of said walls adapted to clamp 'for clasping said ring in adjusted position between said walls, and adjustable work clamping means carried by said ring,

4. A device of the character described comprising a base, said base having spaced vertical walls,the upper edges of said walls being curved, guiding and supporting means carried by said walls, a ring carried by said guiding and supporting means, and means carried by said ring for holding work.

5. A device of the character described comprising'a base, a ring rotatably mounted in said base, said ring being provided with regularly spaced transverse elongated openlngs, a plurality of arcuate clamps within Isaid rin uiding and supporting means D b carrled by said clamps and engaging sald ring, and means'in said alongated openings for adjusting said clamps.

6. A device of the character described comprising a base, a ring rotatably mounted in'said base, a plurality of work clamps adjustable within said ring, an adjusting pin v pro ecting from the rear surface or each of said clamps and. through said ring, guide pins projecting from each end of said clamps parallel to said ad usting pin, and means engaging said ad usting pin for adjusting said clamps. j

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
